The ADP1/2 calculator is designed for one-sided
fuel dispensers and two-sided fuel dispensers equipped with
one nozzle on each side fuelling point. Different fuel can be
dispensed on each side (i.e. through each nozzle).
The calculator can also control LPG and CNG
dispensers.
The qualities of the ADP1/2 calculator are in
keeping with current global standards.
The main advantages of the ADP1/2 calculator
produced by Beta Control Ltd. are its reliability and its high
performance, its low price and its guaranteed quality. The
most outstanding features of the calculators are: the high
flow measurement (up to 500l/min), integrated
Electronic Calibration of meters (EC), Automatic
Temperature Compensation of fuel (ATC was originally
requested for LPG dispensers) and the IFSF standard
communication interface, as well as the proprietary
EASYCALL protocol communication interface on standard RS-485
lines (half-duplex two wire lines).
Setting the calculator parameters guarantees
flexibility. Unit prices for the stand-alone mode, calculator
parameters, meter calibration values, and the ATC (propane /
butane rates) can be set using the wireless keyboards
equipped with infrared communication.
One or two displays can be connected to each
fuelling point. The displays are connected to the calculator’s
internal RS485 bus. In addition to the transaction data, the
other data is displayed on the displays, e.g. all the setting
data, auto diagnostics etc. The displays can be LCD (standard
LCD or backlight LCD) and/or electromechanical Ferranti-Packard
(FP). Optional modules can be connected to the RS485 internal
bus in addition to the displays when requested, e.g. keyboards,
voice module, etc.
The calculator is equipped with non-reset-able
electronic nozzle-totals of the volume, amount and number of
transactions, and at each meter with non-reset-able electronic
meter-totals of the volume. The calculator can optionally be
equipped with a seven-digit electromechanical volume-total
in litres per each nozzle.
The calculator can be set to use two or
three-channels meter pulsers.
A customer pre-set keyboard can be
connected to each fuelling point equipped with the ADP1/2
calculator. Customers can pre-set the volume or the amount of
fuel they want to dispense. The ADP1/2 calculator is also
equipped with an output for vapour-recovery-control
electronics, and with an input for the manual enabling
of the fuelling point in the stand-alone mode at each
fuelling point.
The electronics of the ADP1/2 calculator are
placed in a plastic container that can easily be fixed to the
dispenser head. The input and output wires are screwed to the
pins of the connectors. The type of connectors used enables
the calculator to be changed easily in the event of a fault,
since all the wires stay screwed to the connectors.
A guarantee of up to 4 years is negotiable
for ADP1/2 calculators.
